Instructions how to run

1. Clone the repository

   [email protected]:agh-cs-imbeciles/train-transport-management-system.git
   

2. Go the backend directory

   cd backend
   

3. Install node packages

   npm install

Database

The database is document-oriented, runned on MongoDB, more precisely MongoDB Atlas.

Collections

Contains X collections.
